Monsanto, America's Monster
In first world countries....yes, or close to that much. Agreed. Not world wide.
Mechanized harvest is accepted in "natural" old school farming. Agreed, it would fall under the "industrial farming" methods, but is one of the least damaging.
>1000 acre farms do not count as "family farms" in my eyes, even if they are owned by a single family. So is Walmart, but it's not a mom and pop or family store.
Again, mechanization is not the same as industrialization, but does still do damage by over plowing, etc. I'm talking about monoculture crops, over application of man made fertilizers, herbicides, and pesticides. Grain was farmed "by hand" since farming existed with few problems, but more work involved. The work it takes to rehab a river system because industrial farming runoff contaminated and killed it is FAR more work than the extra work involved in farming using old school methods (which does not mean everything is done with hands, tools and machines have been in use for eons).
Roundup doesn't "break down" completely, and doesn't break down at all if it's washed into river systems and out of the UV light.
Once again, machines aren't all of "industrial farming", they are one of the least damaging facets, and they are not unknown in old school, smaller farming techniques. BUT....overuse of heavy equipment either over packs the soil, making it produce far less, or over plows the soil, making it run off and blow away (see the dust bowl). If it was ONLY about machinery, and ONLY industrial farming used machines, you would have a point, but neither is true.
No, actually overproducing on a piece of land like that makes it unusable quickly and new farm land is needed to replace it while it recuperates (if it ever can). Chemical fertilizers add salts that kill beneficial bacteria, "killing" the soil, sometimes permanently. producing double or triple the amount of food on the same land is beneficial in the extreme short term, and disastrous in the barely long term. (See 'dust bowl')
Man power is far less damaging to the environment than fossil fuels for the same amount of energy. Also, the people would use no more resources because they're in the field than they would anywhere else, so there's NO net gain to the energy used or demand on the environment if they farm instead of sit at a desk, but machines don't use energy when idle, so there is a net loss to the energy required if you replace them with pre-existing people.
Yes, you quoted it directly, buy your characterization of what that meant was insane. You claim they said Monsanto worked on the project (and other things) because they're evil and want to do evil and harm. The video actually said they do these things without much care for the negative consequences to others, and that makes them evil. I hope you can comprehend the distinct difference in those statements, and that your portrayal of what they said is not honest.

The Amazing World of Coral Reefs Fluorescence
I really want to do some UV night diving. It looks amazingly like Avatar to me.

Why are blueprints blue? - Big Questions - (Ep. 206)
I actually made a cyanotype print in high school chem class (a long time ago!). The process is that you make the solution, paint it on the paper, let it dry in the dark, put the object or negative on top, expose to sunlight (or UV light), and then rinse it in water to fix the print.
I also found this set of instructions which confirmed what I remembered

Howdy - sorry for the delay, was traveling on business. The issue you are referring to below with regards to reusable water bottles is I believe related to the type of liner (thin coating of polymer based material that is coated on the inside of some but not all of these bottles). In most cases when polymers come in contact with food (incl. water) the concerns are usually not in the polymer itself, but in some of the additives (processing aids, plasticizers, anti-oxidants, UV stabilizers, pigments etc) that in some cases have negative impacts on some human metabolic processes. I would emphasize 'some'. The recent outrage over BPA is not supported unequivocally by scientific evidence, but there is enough uncertainty to move away from it as a plasticizer in PET bottles. If one was to use a food grade polyethylene or polypropylene water bottle, requiring no liner, and totally suitable as a water bottle, then there is no concern at all with the long term use of this material in water bottles. Next time you go through the grocery store, have a look at all the packaging - films on processed meets, stretch wrap on fresh meat cuts, all of your cold dairy products - the vast majority of these are made from one of either polyethylene or polypropylene, with a smattering of polystyrene and polyvinylidene chloride thrown in. All perfectly safe.
As for how the balls are made - these are blow molded. If you have a look at the plastic baseballs made for kids that come with a big fat plastic bat (or really any hard plastic ball that you might find at Wal Mart or Toys'R'Us, you'll see the small ridge that runs equatorially around the circumference of the ball (that's the parting line where the two mold halves come together) and somewhere on that line there will be either a little tiny hole or a small protruding knob that used to be the parison where the air was injected into the small plastic glob forcing it to the walls of the mold like an expanding balloon. This is the same type of molding that makes your liquid dishwashing detergent bottle, plastic ketchup and mustard containers, and plastic milk jugs. Hope this helps a bit. cheers
I admit this is something I know little about so I have a couple of questions if you don't mind... There seems to be a concern about what reusable water bottles are made of. So you're supposed to use a certain type or the plastic (and this may be the wrong term) leeches into your water and then I don't know exactly what, but you probably die some horrible death maybe like in the toxic avenger. So one question is... Is that true (or maybe a less exaggerated version)? The second one I think you may have answered is... Are these injection molded? I can't comprehend how these would be made. I think I need a How it's Made to wrap my mind around this. Thanks.
Reservoir No. 2 - Shade Balls
What they said was that only black would survive the UV radiation, and they expect these ones to last about 10 years.
I would've liked more of an explanation than that myself, but haven't gone looking for one.
[...]Some folks have asked why they are black... which is indeed odd and perhaps not conducive to minimizing evaporation... and I can only imagine that the source of the polymer used to make these could be a scrap stream as they would be wanting to keep costs low, and in comingled streams the ultimate color is often dark - black, deep blue, browns etc. - when the stream is extruded and pelletized. If money was no object and they had to go with balls, then black would likely be the last choice, not the first (white - well loaded with inexpensive TiO2, or in some future universe... reflective silver!) Have fun.

3D printing 100X faster and inspired by the Terminator movie
The filament style of 3d Printers are cheap to operate and can be made to nearly any size.
A resin printer needs a photopolymer, something that solidifies when exposed to UV light. They also need a fairly strong projector and lens, which limits their build area.
A filament printer can use a lot of various materials, the most common being PLA (a bioplastic made from renewable plant materials) and ABS. There are many other materials, some are specialty that have an almost rubber like flexibility to them, to a filament that is made from wood and a binder, which results in an printed object that can be sanded and stained. And, since you are moving a print head, the only limitation to the build size is how big you have made your printer.
I did not know that; so---why did the deposition 3Ds come into being? Was that about cost of materials, even though they are apparently 100X slower?
This is quite educational for me.
Fascinating autism test for "theory of the mind" in children
Hmm, i don't know if it is that.. I see this all the time too (i tutor and do support to one 3D design software). Usually it is more about the person not knowing the right terms; they don't know what questions to ask or how to identify the problem, the steps that we "computer literate" know to do when we encounter a problem.
Fortunately we have screencaps, allthou often you need to teach them how to make them. I usually try to be thorough, even thou it means spending a lot of time explaining, trying to show them the way for them to solve the problem..
But then again, my "clients" are not totally illiterate which makes it a bit easier but then again, 3D design has very special concepts and terms you need to know; you just can't say "your UV mapping is screwed" when they hardly know what a vertex is.. So you have to explain the very basics of it to solve a problem that takes about a minute if they would send me their models.. I do make them all watch about an hour of videos and read few pages, very often they figure it out once they understand the logic and know the basic terms; they can use google to find it out then.. Teach a man to fish type of strategy.
But it's not that they have some mental defect, they just don't know how the freaking machine works, they have no other words to use but vague, totally gibberish. And they are afraid of using some term they are not 100% sure if it's the right one, a bit like talking a strange language.
I've always said this "Sally-Anne" scenario doesn't just reveal something about the autistic mind. I see it in people every day, particularly as an IT tech. Some people just don't have an intrinsic understanding that others are not seeing the images in their head when they are describing something, using vague pronouns and ambiguous terms that make sense in their head. They are incapable of "reading my mind" to know that I can't read their mind.
They don't seem to understand that others were not in the room experiencing their computer problems along with them, and then act put out while I ask 20 questions to ask them to describe what the hell is going on. Usually with an impatient air of "why am I asking all of these redundant questions? "
And it has nothing to do with being computer literate, and everything to do with not recognizing that I don't share your perspective without some more info. I work with many techno-phobes who don't have to be coached like that.
BTW, repeating"I can't log in, it won't let me" has been used to describe countless scenarios, you might as well ask me to guess which card you just picked out of a deck.
